Sunshine is believed to increase the release of serotonin in the brain. Serotonin, often referred to as the feel-good hormone, is associated with boosting mood, lowering feelings of anxiety, and helping a person feel calm and focused. Exposure to sunshine and light during the day and darkness at night helps us maintain a healthy circadian rhythm, which is essential for good mental health. Sunshine also helps your body make vitamin D. Vitamin D is an important nutrient for your bones, blood cells, and immune system and helps with the absorption of calcium and phosphorus. Go out and enjoy the sunshine safely; it is good for your health!
